Ripping Back

SO, knited a pair of wrist warmers last weekend, hated the first one, tried to rip out from the beginning since the secnd half looked good. I know that doesn't work, why did I even think to try? threw the entire thing in the trash and will knit another one. uck. Which made me really think about the huge (for me) jacket I started knitting last summer, about 1/4 done, see some problems and thought oh, I'll just rip out and knit back. So now I know, don't even bother trying, rip out the ENTIRE thing and start over. almost makes me want to cry but then again, practice is supose to be a good thing. Think I'll start another sweater in the meantime so I have something successful, and will probably be done sooner.
